You could argue that just about every player on the Oakland A's roster is a fantasy baseball sleeper.

Everyone on the young pitching staff is attractive in Oakland's monstrous Coliseum. That home ballpark will also likely drive down the draft prices of A's hitters, despite the fact that Oakland finished fourth or higher in runs, RBIs, doubles, homers and slugging percentage last year. In short, there's no shortage of value in Oakland.

But if we're looking for a true "sleeper" who could overcome the Coliseum and flourish in the A's surprisingly productive offense -- like Josh Reddick in 2012 and Brandon Moss in 2013 -- it could be 1B/DH Nate Freiman.

The 6-8, 250-pound Freiman is a behemoth in the batter's box. He showed his power potential in 2012 while with the Padres' Double-A affiliate, hitting .298/.370/.502 with 24 homers and 31 doubles. That was one year after hitting .288/.354/.487 with 22 homers and 35 doubles in High-A. He also showed solid strikeout and walk rates at every stop in the minors.

In December 2012, the Astros took Freiman in the Rule 5 Draft, but a logjam at first base kept him from making the team the following spring. He was claimed off waivers last March by Oakland, where he served as a bench bat for most of 2013.

This year, Freiman could be in line for more playing time between first base and DH, making him a nice power sleeper. Like Reddick and Moss before him, the righthanded-hitting Freiman could be initially stuck in a platoon. But considering that Daric Barton would likely be the lefthanded half of that platoon, Freiman has a decent chance to earn everyday at-bats.

If he does, keep him in mind as a cheap power grab in AL-only and deep mixed leagues.
